Obama administration officials unmasked officially classified documents and then leaked the material to the media. From Sara Carter at saracarter.com:
In 2017, information published by this reporter and John Solomon, then with Circa, a online news organization under Sinclair Media, exposed that former Obama national security advisor Susan Rice had unmasked a number of U.S. officials connected to then President Donald Trump’s campaign.
On Monday night, reports surfaced, first with ABC News and then others, that the acting Director Of National Intelligence Richard Grenell had authorized the declassification of the list of senior Obama officials that had unmasked Americans exponentially in the last months of the Obama administration.
A U.S. official familiar with the declassification process confirmed to SaraACarter.com that the list of officials has been declassified and should be made public shortly. In May, 2019 President Donald Trump authorized the Department of Justice to declassify the list, as well as all the other documentation pertaining to the Foreign Intelligence Surveillance warrant used to spy on short term campaign volunteer Carter Page. Department of Justice Inspector General Michael Horowitz revealed in several recent reports that the FBI and DOJ failed to validate the evidence used to obtain the warrants to spy on Page and omitted evidence that would have stopped the secret court from authorizing the warrant to spy on the campaign.
The Flynn Unmasking List of Obama officials by RGrenell is below and includes VP Biden. Pretty incriminating.
